Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the engine is cool.
Gather necessary tools and parts.
Disconnect the negative battery terminal for safety.

2. Check Oil Level and Condition

Remove the dipstick and wipe it clean.
Reinsert the dipstick fully, then remove it again to check the oil level.
If oil is low, top off with the manufacturer-recommended oil type (5W-20 or as specified).
If oil appears dirty, proceed to change the oil and filter.

3. Change Engine Oil and Filter

Place an oil catch pan under the oil pan.
Remove the oil drain plug using a socket wrench and allow the old oil to fully drain.
Replace the old oil filter with a new one, ensuring the rubber O-ring is removed with the old filter.
Install the new oil filter, tightening it according to the manufacturer's specifications (typically hand-tight).
Reinstall the oil drain plug and torque it to the specified value (usually around 25-30 ft-lbs).
Fill the engine with new oil through the oil filler cap, using the recommended oil type.

4. Replace Oil Pressure Sending Unit (if faulty)

Locate the oil pressure sending unit (usually near the oil filter or on the engine block).
Disconnect the electrical connector from the sending unit.
Use a wrench to remove the old sending unit.
Install the new sending unit, ensuring it is tightened properly (typically 15-20 ft-lbs).
Reconnect the electrical connector.

5. Final Checks

Reconnect the negative battery terminal.
Start the engine and let it idle.
Check for leaks around the oil filter and sending unit.
Monitor oil pressure via the dashboard gauge.
